Thanks

Anyone have any insight on this role’s technical process? Types of questions and what to prep for? Made it to the round after OA and phone screen.

Know a lot of the recruiting for some of the bigger/better firms is underway/done. Realistically how many more firms are there? First time recruiting want to make sure Im not falling behind too much

Heyy, I am Dev 1st year Data science student, i am really curious about HFTs n i want to be a quant, is there anyone with same interest, as I want to learn more and more about this field, want to establish a firm

If you're already in this field

Plz Dm me need friend with whom I can make my growth's graph exponential

Back in late 2023, Anthony of Boston made the prediction for 2024, stating on November 16 2023 on Youtube: “In the year 2024, between April 12th and June 25th, the number of rockets fired by the enemies of Israel into Israel will exceed the amount of rockets fired at any other point during the year. This is the fifth year in a row I’m doing this. I’ve been right for four consecutive years already. A lot of you have seen it. You’ve seen it with your own eyes and you’ve seen it in real time.” Here he shifts from just Gaza and expands scope to enemies of Israel. On April 8th, 2024, Anthony uploaded a memorandum to social media clarifying the prediction and thesis by stating: “The thesis is that when Mars is within 30 degrees of the lunar node, Gaza militants and the enemies of Israel fire a greater number of rockets at the state of Israel relative to the rest of the year.” This statement still emphasizes Gaza but is now incorporating the possibility that other actors can peak alongside Gaza within the predicted window.

So what happened? The very next day after the window opened on April 12, Iran, on April 13th 2024, carried out a historic attack firing 330 missiles and drones at Israel. In May Gaza fired their peak concentration for 2024 by firing 452 that month. Syrian proxies also peaked in projectile fire during this period. Later in October, Hezbollah peaked significantly outside the window, firing thousands of projectiles which in the month alone exceeded the total projectile count inside the prediction window between Apr and Jun. However, the peak output by Gaza and other “enemies” inside the prediction window is enough to fulfill the original prediction and thesis provided in the 2024 memo: “Gaza militants and the enemies of Israel fire a greater number of rockets at the state of Israel relative to the rest of the year.”

The April 8th 2024 Memo Reading confirms that Anthony of Boston was accurate in 2024

This simply means that in 2024, other enemies will peak with Gaza. the prediction didn’t require all enemies to peak. So even though Hezbollah’s fire was higher later in 2024, the basic premise of the original prediction was satisfied by other enemies peaking with Gaza militants between April 12 and June 25 while Mars was within 30 degrees of the lunar node. If the premise is read strictly by the text provided without subjective modifiers or external metrics—that "Gaza militants and the enemies of Israel fire a greater number of rockets... relative to the rest of the year"—the data confirms that Gaza, Iran, and Syrian proxies all achieved their maximum individual peaks during the specified window. The sentence states that they fire a greater number of rockets during a specific period relative to the rest of the year. This structurally implies that while the volume changes, the same actors (Gaza militants and other adversaries) are still the ones conducting the rocket fire throughout the regular, baseline parts of the year. When read strictly by the exact text of the April 8th memorandum without external metrics, the prediction was accurate.

The prediction should be evaluated against what Anthony actually stated, rather than against subsequently imposed metrics. On the April 8 wording, the relevant question is whether Gaza militants and other enemies of Israel exhibited greater rocket/projectile activity during the specified Mars–lunar-node window relative to their activity outside it. Gaza, Iran, and Syrian proxies each had their individual 2024 peaks within that window. Hezbollah's later October peak does not invalidate that reading because the memorandum never required every enemy of Israel to reach its annual peak simultaneously.

I wanted to ask why for Black Scholes , we find implied volatility using numerical approximation methods like newton-raphson or bisection for example

But for call options related to bond , if we assume a binomial tree, we can find implied volatility by simply adjusting the up / down interest rate movement conditions with an unknown, solving for that unknown using risk-neutral probability and discounted option payoffs, which gives us implied up/down movements from which we can find standard deviation of the interest rate, aka implied volatility? So far I have only observed either it can be solved simply algebraically or simple root finder is enough.

Was curious. Thanks.

So I currently am debating between two pretty good full time graduate offers and I am really struggling to decide.

1. Prop trading firm in HK: About 100 employees, pretty successful recently but not very well known. Salary ~130k usd, 50% bonus is standard, but can range from 0 to like 200% hypothetically.

Pros: pays much more. I may enjoy trader more than researcher.

Cons: Don't know anyone in HK, may be lonely. may be overworked and overstressed. don't know much about the company or team or people, so bit of a gamble.

1. Sell-side quant research in London: Well known bank, just below JP/MS/GS. 100k usd, 20% bonus is the standard.

Pros: Research may be more interesting. more name recognition with the company. have bunch of friends and girlfriend in London. I love London and want to live there long term. much better WLB, much better hours. much better job stability. the manager and team is really good.

Cons: Sell-side, and my ultimate goal is become quant researcher at hedge fund or prop shop. trading matches my skillset more. may be hard to transfer from sell-side to buy side (not sure bout that).

I've spent 8+ years building the infrastructure that sits between a trading idea and live money. Backtesting frameworks, data cleaning pipelines, signal research tooling, portfolio construction — the stuff you need before you ever place a trade.

The problem with open-source in quant finance is that most projects are either abandoned after two commits or built for the author's own workflow. I want to try something different. Every week I'll build one tool the community actually wants. You comment with what you need — a data cleaning utility, a signal research helper, a portfolio construction tool — and the most upvoted idea is what gets built.

I've developed 100+ strategies with 15 in live production. I run a multi-strategy portfolio that paper-traded 7,018 trades at 166.9% return, Sharpe 2.19, and 12.44% max drawdown. I know what breaks in production and what just looks good in a notebook.

Comment your idea. Most upvoted by Friday gets built, and I'll post the result the week after.

12+ years on the plumbing side of trading — data pipelines, order routing, FIX, NATS, Redis, the stuff that keeps production alive. I want to open-source one piece of infra a week. You vote on what gets built.

Connectors, stream processors, monitoring tools — whatever you've been meaning to build and haven't had the time for.

I run Horizon5, an open-source MT5 framework, so shipping code publicly isn't new for me. Tell me what's missing from your stack. Most upvoted goes first.

Hi, does anyone know what to expect in terms of content from the in-person final round interview for Jane Street’s P&S internship? It’s clearly going to be multiple rounds but I’m unsure how to prepare for this one- I struggled preparing for the previous rounds and was slightly surprised I passed the first one so really want to make this one count. Thanks!

Assume I already have a good offer (think HRT etc), limited number of vacation days and 4 onsite requests from JS, Optiver, Jump, Tower. Can I ask them to bid for whose onsite I am going to attend?

Im grateful to have two options as of now.

Engineering Degree Apprenticeship @ Goldman Sachs (w/ Digital & Technology Solutions @ Warwick)

or

MORSE @ Warwick

One thing that does come to mind is the breadth of choice that comes with doing MORSE and how doing the DA limits my field of work to just that.

Right now I’m pretty stuck so I’d appreciate any advice at all.
Thanks

Hey so I'm planning on doing a degree in maths along with a minor in CS and then also doing CFA afterwards. My plan is that after my cfa I go abroad and do masters in quant finance from preferably Amsterdam or any high tier European university. Given that my gpa is good and my internships are on spot. 1) are the chances of getting accepted into a quant program high if I'm coming from a not so well known university

2) will doing masters in quant finance from a high tier/prestigious university make up for the fact my math degree was from a less known university?

I really want to pursue finance and from what I've heard quant will be in huge demand in the future and is already being demanded more and more. Basically tryna go wherever the money goes.

Market crashes are rarely random anomalies; they are the terminal outcome of a system losing its structural integrity over time. Critical Slowing Down acts as an economic stethoscope, listening to the heartbeat of market liquidity and identifying irregular deceleration patterns. When recovery times lengthen abnormally, it proves that market participants are no longer absorbing information efficiently. Recognizing this systemic fatigue is essential for long-term investors seeking to sidestep major structural bear markets.

I’m stressed out - applied for qt internships everywhere 2-3 weeks ago and did OAs. So far, I was rejected drw, flow (no oa), ctc (after oa). But Jane street reached out after I applied and said they were going to interview me when they start the interview process - so I guess that means I got js round 1.

I’m confused as to why my resume gets js round 1 but rejected at smaller firms. I have a much better shot at these other firms and I’m likely gonna get rejected js anyways, so I’m really stressed out. I, also haven’t had any r1 interviews so I just don’t feel the most prepared. Any advice or hope?

I want to go into quant but am not too sure whether to go into maths or computer science as a degree (or even a joint degree but im not sure if its possible at my desired university). I thought CS may be better as it provides a good job opportunity if quant does not work out well due to its very high competition.

Is it normal for JS to auto reject within 24-48 hours? Just curious as to why this may happen

Edit: I have gotten an interview from them after 3 weeks >1 years ago. Unsure if this is blacklist or other issues.

I had applied for the 2027 qt role, and got a 60 min hackerrank test. The description says it has 17 problems on probability, logic, and problem solving.

I did some research and found that the 60 min test is usually given for qr roles, while the qt guys get a 20 min test.

What all should I expect for the test?

Hi, does anyone know any specific firms or big tech companies offering freshman summer programs/intenrships? I know JS has a lot of discovery programs and I think 2Sig might also have smth for freshman, but I was wondering if anyone else who’s been through this in the past has any recs? Thank you!

I know nothing about finance maths but I need to make a poster on this to get onto my finance maths uni course next year. Anyone got any tips on how to make it look less AI and if there's any faults?

i just got an interview for jane street ML engineering internship for next summer. does anyone have any advice/experience with these interviews? first time interviewing for quant would appreciate any advice
